To assess expected transit signals we created synthetic light curves using the batman package [1]}, analysing them as above. Planetary radii, \(R_{\rm P, Earth-like}\) , are estimated from the minimum masses \(M_{\rm P}\sin {i}\)  given by [2]}, assuming \(i=90^{\circ }\)  and the Earth-like rocky planet models of [3]}. Semi-major axes of (assumed circular) planetary orbits are as given by [2]}.
We adopt \(R_{\ast }=1.26 R_{\odot }\)  [2]} with a quadratic limb-darkening law (\(u_{q}=0.3216\) , \(v_{q}=0.2301\) ) appropriate for a star with \(T_{\mbox{\scriptsize {eff}}}=6200\)  K and \(\log g = 4.5\)  [6]}.
